I carry this with whatever light I decide to carry. It rotates to carry horizontally , vertically, or at a 45 degree angle. I especially like this feature as you can hold the light in "someone's" face and have your hands free for"other" purposes. I have had the light get turned on accidentally a couple times. This has not happened with tail cap clickys though. They are available at Gander Mt last time I checked,
+1 for the Nite Ize, its what i carry at work/play. Lowe's also carries them, or at least that's where i got mine last year. It was $9 if memory serves.
I have the stock nylon pouch for my Fenix somewhere. Let me know if you want me to dig it out. You can have it. I'll be in your neighborhood Friday sometime.
Get a Flashlight Carrier from Galco. They are leather with a break-away snap that allows very rapid access to the flashlight. Legendary American-Made Galco Quality. You can get one for about $20.
